Just found an interesting snippet on facebook with Richard D Wolff. He argues
that the rise of BRICS and the fall of the G7, he focusses on America and China.

He states that the G7 GDP is 28% of world output while BRICS is 35%.

On a different snippet of the same interview he states that the US and China
are on two different trajectories, The US is on the downward and China is on
the upward trajectories, they both are the key compenent countries in both G7 and BRICS.
